Specification of Letters Patent. Fawn-ted Aug. 2-1. t 909. Application filed November 12, 1908. Serial No. @2371.

duced portions of the hearing-rollers, at the ends, are of less diameter than the reduced end-portions ot' the spacing-rollers, so that the reduced ends of the hearing rollers do not engage the ribs of the sleeve while the ends of the spacing rollers do engage the ribs. These ribs, therefore, torn] supportiug traclrs for the spacingrollers and guides for both rollers. luclesing the reduced ends of both sets 0? rollers are the end-caps 10 which are pressed over the respective ends of the sleeve 3 and abut against the outer sides of the track-thinges 4- hut'. do not conlle it known that l, lunnrr T. litmus, a citizen of the United States of America. residing at Buffalo. in the county of Erie and State of New York. have invented certain new and useful improvements in itoller- Bearings of which tlu. following is a full and clear specification.

' My invention relates to improvements in the construction of an antitriction hearing, and-has for its object to provide a. hearing which will he inexpensive and simple in construction, and in which at the same time, the friction shall he reduced to a minimum.

It is also an object. of this invention to provide a roller bearing in which the hear ing rollers will be evenly held and in which the parts can be assembled and handled a unitary body.

A turther object of this invention is to nals of the rollers. Each end-cap consists of a ring-like plate having an inwardly ex tending flange 10 which overhangs the reduced ends of the rollers and forms, in cooperation with the track-flange 4, a continuous annular channel opening inwardly. Each end-eap is removably but tightly held on the sleeve by means of one of the fastening screws 2. this screw being placed in a notch in the end of the sleeve in order that it may abut against. the outer end ofthe end-cap and thus hold it tight y against the track-flange. These sercws,' therefore, serve to not only fasten the sleeve to the shaft but also to lock the end-caps'removably in posilion.

the use of retaining rings, and which, when the outer box or casing member is removed, will retain the rollers in position on the hearing sleeve or shaft and thus prevent their disarrangement.

Vith these and other objects in view, the invention may be embodied in the form do scribed in this specification and shown in the accon'ipanying' drawing in which- Figure l is a horizontal sectional view through a box for a shafting; Fig. is an end View of rollers with (lUSt--52[) ll removed; and Fig. 3 is a transverse .eetion through the center of the hex. 1

'Referring to the drawings by reference characters, 1 designates a shafting with radial holes drilled andta 'iped therein to receive set-screws 2 for holding removahly but rigidly the sleeve 3 which is provided near each endwith an annular rib l: to term guides and supports for the reduced ends (S of the spacing-rollers These ends (3 are small enough in dian'ietler to prevent the of the load-rollers do not contact with the enda-aps or the track-flanges while the journal is in use: these r duced ends of the loadrollers simply serve to hold the parts in assembled relation when the hearing is removed from the box or the sleeve from the shall. it will he ohsrrvetl, howtwor that; the reduced ends of the spacing-rollers run over the center of the shaft and upon the inner faces of the end-cap flanges while they are passing underneath the shaft, so that the track-flanges and end caps serve with respccl to the spacingrollers not only as guides and supports while the journal is in use lint also as retaining devices while the journal is out of the lam.

It will he observed that. l do away with all suspended retaininga'ings and the main diszulvantages attendant upon their employ ment in a hearin of this type. and it will spacing-rollers in those portions of their he observed further that. my invention renlength which bear against the sleeve and dcr it a very simple operation to a emhlo the box or outer member ll, while the re the parts ol the hearing. ll will he 'ol but large enough to prevent the body of the spaeingaollers from engaging the sleeve 3 The bearing-rollers 7, provided near the ends thereof with reduced ends 8 which are small enough in diameter to avoid contact with the ribs of the sleeve. The hearingrollers have a greater diameter than the tact with the end-faces of the reduced jourit will he oliserved that the reduced ends on the tracloliangcs lwhile the are passing;

served also that. the rollers will be held in I place with the utmost exactness and that, therefore, the friction will be reduced to such a minimum that; a lubr'cant is not only rendered unnecensary but would tend to increase friction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, ie

' 1. In combination. a slialt,-a sleeve litted thereon and provided with annular tracktlangcs and a notch in each outer end, an end-cap reinovably placed on each end of said uleeve and forming in conjunction with the adjacent tri'iclet iange an annular chanucl, a :lastcning screw at each end of the sleeve, said screw engaging said notch in the end of the sleeve and abutting against the adjacent cudcap, anlit riction' rollersi having their reduced ends Working in said 1 channels, and an iuclosing box.

L. In combination, a shaft, a sleeve provided with annular trackflanges, an endcap on each end of the sleeve forming in coi'ijunction with the adjacent track-flange this 26th day of October 1908.
